System Design Deep Dive (Real-world Systems)

Learn how real-world backend systems are designed at scale based on actual production experience.

We’ll cover:

• Designing scalable systems (80M+ users mindset)

• API design and service architecture

• Caching strategies (Redis, Caffeine)

• Event-driven systems (Kafka)

• Trade-offs and real-world decisions

This is NOT theoretical system design—this is how systems are built in real companies.
